fs: sdcardfs: Declare LOOKUP_CASE_INSENSITIVE unconditionally



Attempts to build sdcardfs as module fail with

fs/sdcardfs/lookup.c: In function '__sdcardfs_lookup':
fs/sdcardfs/lookup.c:243:5: error: 'LOOKUP_CASE_INSENSITIVE' undeclared

This occurs because the define is enclosed with #ifdef
CONFIG_SDCARD_FS_CI_SEARCH. If SDCARD_FS_CI_SEARCH is configured to be
built as module, this does not work. Alternatives would be to use #if
IS_ENABLED(CONFIG_SDCARD_FS_CI_SEARCH), or to declare SDCARD_FS_CI_SEARCH
as bool, but that does not work because the define is used unconditionally
in the source.

Note that LOOKUP_CASE_INSENSITIVE is only set but not evaluated in the
current source code, so setting the flag has no real effect.
