firmware: fix build errors in paged buffer handling code

Browse Source 
fw_{grow,map}_paged_buf() need to be defined as static inline
when CONFIG_FW_LOADER_PAGED_BUF is not enabled,
infact fw_free_paged_buf() is also defined as static inline
when CONFIG_FW_LOADER_PAGED_BUF is not enabled.

Fixes the following mutiple definition building errors for Android kernel:

drivers/base/firmware_loader/fallback_efi.o: In function `fw_grow_paged_buf':
fallback_efi.c:(.text+0x0): multiple definition of `fw_grow_paged_buf'
drivers/base/firmware_loader/main.o:(.text+0x73b): first defined here
drivers/base/firmware_loader/fallback_efi.o: In function `fw_map_paged_buf':
fallback_efi.c:(.text+0xf): multiple definition of `fw_map_paged_buf'
drivers/base/firmware_loader/main.o:(.text+0x74a): first defined here

[ slightly corrected the patch description -- tiwai ]

Fixes: 5342e7093f ("firmware: Factor out the paged buffer handling code")
Fixes: 82fd7a8142 ("firmware: Add support for loading compressed files")
